1. The function of battery
The battery is the core part of the vehicle's electrical system. It can not only provide energy when the vehicle is started, but also provide energy for the entire vehicle's electrical equipment.
Compared with other parts in the car, the battery has a complex structure and is greatly affected by factors such as temperature, humidity, and car usage habits, so it is more "fragile".
2. Symptoms of battery replacement
1) The battery fault light comes on
If the battery fault light comes on in the vehicle dashboard, it means there is a problem with the battery charging system and the generator cannot continuously supply power to the battery.
At this time, there may be a problem with the battery itself. It is recommended to have it checked by a professional technician at an authorized service station and replaced as needed.
2) Battery bulge and leakage
If the battery bulges or leaks, it needs to be replaced in time. If you continue to use it without any care at this time, there may be safety hazards. It is recommended to go to an authorized service station for inspection and replacement as soon as possible.
3) Continuous ignition failure or difficulty in ignition
In addition to troubleshooting the spark plug failure, if each start requires multiple ignitions or difficulty in starting, it means that there may be a problem with the battery. In this case, you need to go to an authorized service station to check and eliminate the fault in time.
4) Batteries that have experienced multiple power losses
Some car owners may continue to use vehicle electronic devices after turning off the engine. If this continues in the long run, it may easily cause the battery to over-discharge, which directly affects the service life of the battery.
If the battery is over-discharged (i.e., depleted) many times, it is recommended to check and replace it to avoid affecting future use of the car.
5) Daily maintenance
In fact, daily maintenance of batteries is very simple. Doing the following points daily can slow down the aging rate. Clean the terminal oxide regularly to maintain good contact; avoid using vehicle equipment for a long time after turning off the engine to prevent excessive discharge.
If ignition fails, avoid continuous forced starts; if parked for a long time, start charging in a timely manner. In addition, the battery is a consumable part and it is recommended to check and replace it regularly.
6) Voltage changes before and after starting
The normal voltage of the battery is about 12V. After starting, due to the charging of the generator, the voltage will increase to about 13-14V. Many vehicles have a voltage detection function. Paying attention to the voltage before and after starting is also a good way to judge the battery life. Vehicle If it is lower than 12V when not started or lower than 13V after starting, you should consider whether there is a problem with the battery.
The car battery is always a consumable item and it has a lifespan. The service life of the battery is generally about 2-3 years. When the replacement cycle comes or when your vehicle shows the above symptoms, you should go to the repair shop to check and replace the battery in time! Otherwise, if you suddenly can't get a taxi one day, you will have to ask others for help or wait for rescue.
